Current Nova version does not support computes older than Xena but the minimum compute service level in your system is 56 and the oldest supported service level is 57

I have upgraded wallaby to Xena on Ubuntu 21.04 and nova encounter with following error.

Solution:

mysql -e "update nova.services set version = 57 where deleted = 0;"

Reference patch but for Victoria:

[Elod Illes (elod-illes)]

Hi Satish,

To me both the error message and the workaround suggest that the upgrade went from Wallaby to Yoga and not Xena.

Xena would require minimum compute service level 56 (which you have according to the error message), which is Wallaby. But the error message indicates (requires 57, Xena) that the version is Yoga, as these minimum requirements are there.

If this is true, then this is not a bug, as Yoga is N+2 compared to Wallaby. Can you please double check this?

[Satish Patel (satish-txt)]

Elod,

I have already bump it to 57 by hand using mysql update. But i have one more cloud environment running on Wallaby and i did query and found following version

MariaDB [nova]> select version from nova.services;
+---------+
| version |
+---------+
| 56 |
| 56 |
| 56 |
| 56 |
| 56 |
| 56 |
+---------+

Does that indicate 56 is wallaby? I am confused about versioning stuff.

[Diko Parvanov (dparv)]

faced this during focal/ussuri -> jammy/yoga upgrade twice already

[Kamal Bhaskar (kamalb)]

Faced this issue when upgraded from focal/wallaby to focal/xena.

Nova API stopped working and was getting response as 500, found below errors in nova-conductor logs:
